Not at all buddy, thanks for ur input
And to everyone else who has chimed in, thanks..
Haha no one knows about my hobby except the missus,
So this is the only place I can discuss gardening issues.
I am exploring all these exotic causes after these 3 months but I cant help but feel the problem is a basic one and I am just missing it staring me right in the face...
The brown leaf tips suggest nutrient burn, but the leaves get lime green before the tips turn brown. Especially the veins... Nutrient toxicity should turn the leaves darker, right?
